Bispecific Antibody Design & Assembly

Design and validate bispecific-antibody constructs end to end: format and geometry selection, exact sequence-topology assembly (tandem VHH, DART, KiH common-light-chain, the three CrossMab crossovers, DVD-Ig), interface-aware full-complex structure prediction against both intended targets, and a transparent developability/liability screen. Every construct is hash-bound with complete provenance.

Maturity: Research preview — outputs are computational hypotheses for experimental review, not evidence of expression, chain pairing, binding, affinity, specificity, or function.

Deliverables: validated chain topology · full-complex two-target confidence assessment · developability report · provenance-bound artifacts and explicit limitations.
